WITHDRAWING SKELETON OVEN.

Specification of Letters Patent.

Patented June a, rare.

Application filed January 29, 1912. Serial 1T0.673,981.

, such as a stove, to facilitate placing cooking vessels, or anything else which is to be subjected to the action of heat, in the oven and removing the same therefrom; and it comprises certain novel features which will be fully described in the following specifica ition andpointed out in the claims appended thereto.

Reference is to be had to the accompany; ing drawings forming a part of this specification, in which the same characters ofreference indicate the same parts in all the views. 1

Figure 1 isa perspective view of a stove to which my improved rack is applied; Fig.

, 2 is a vertical section taken through; the oven of the stove and my rack applied thereto;.- Fig. 3 is a vertical section taken on a plane passing along one side of the oven to show, the interior construction of the guides for my improved frame or rack; Fig. 4 is a horizontal view taken on the line 4-4 of Fig. 3 and 44 of Fig. 5-, in both instances looking in the direction of the arrow; Fig. 5 is .a transverse vertical section taken through the guiding means, and showing the position of the same when the rack is pushed part of the way into the oven; Fig. 6 is a detail view of the removable bar 'at the top of the rack in the front of the same; and Fig. 7 is a perspective view showing in detail how the guides are connected together. On the drawings, the numeral 1 represents an ordinary stove provided with an oven 2 which is closed by means of a door 3. The supporting frame or rack is indicated at 4,. and this frame or rack is designed to be pushed into the oven to enablethe door to be closed upon the same, or to be drawn forward so as to project outward from the open mouth ofthe oven, as shown in Figs. 1 and 2. When in projecting position, the cooking vessels can be placed thereon and the frame 1 then pushed back into the oven to permitthe door to be closed and the contents of the vessels carried by the frame to be cooked.

The construction of the rack or frame 4 comprises a U-shaped member in the front of the rack indicated by the numeral 5.-

This U-shaped member supports at its upper ends a cross-bar 6 having lugs '7 projecting downward from its ends and fitting in aper- I tures formed in lugs 8 carried on the inside of thearms of the U-shaped member 5, adjacent the upper ends thereof. At the rear of the rack or frame 1 is a rectangular-shaped member 9 which forms the rear of the rack, and this member 9 is connected to the member 5 at its upper ends and also the lower ends of the vertical portions by means of longitudinal metal strips 10, of which there are two on each side. On the inside of the rectangular-shaped member 9 and the inside of the arms of the U-shaped member 5 are arranged lugs 12 to carry an extra grid on which the cooking vessels are placed, if an extra grid is needed. Normally, however, only two grids will be required. and these are shown at 13, supported at the top and bottom of the rack or frame a.

The numeral 14; represents a partition which is secured tothe rear edges of the rectangular member 9, and is of nearly the same extent as the mouth of the oven, so that, when the rack is drawn into projecting position, as shown in Figs. 1 and 2, this plate 14 will close the mouth of the oven and prevent the escape of the heat therefrom.

The strips 11 at the sides of the rack on the top thereof are bent upward, as shown at 15, and inward, as shown at 16, and then upward again, as shown at 17. The sections 17 are secured to tubular-shaped guides 18, which slide in movable C-shaped guides 19.

.TheseC-shaped guides in-turn slide in other C-shaped guides 20, which are mounted in the sides of the oven,'as shown. The tubular guide 18 has a lug 21 projecting therefrom to engage a shoulder 22 formed on one edge of the C-shaped guide 19 adjacent the middle thereof; and the @-shaped guide 19 has a similar lug 23 at its inner end, to en gage a similar shoulder 24 formed on one edge of the C-shaped guide 20. These lugs and shoulders prevent the rack from being 1 withdrawn any farther forward than is indicated in Figs. 1 and 2, and thus prevent the rack from being detached from the oven entirely. The guides 18 also have lugs 18 and push them back into the guides 20.

Further, the guides 18 are closed at their front ends, as shown in Fig. 4.

In practice, my improved supporting rack or frame is provided with the guides l8, l9 and 20 along the upper edges of its sides.

, The lower parts of the members 5 and.9 are near the bottom of the oven, and no guiding means along these edges are necessary. The

entire frame is of course made of metal. 7

Each of the guides never projects more than half way from the guide into which it telescopes, which arrangement admits of the skeleton oven being withdrawn and held rigidly in suspension, entirely outside of oven proper, thus allowing of easy access, either at the sides or end, to any contents of the oven, for the purpose of changing the position or removing the same, during the process of cooking or heating.

This device is intended for use in connection with any oven the contents of which require to be handled or moved in any way while the oven or contents are in a. heated state. But its peculiar adaptability to cookstove or range ovens will at 'oncebe apparent when it is remembered that an ordinary range oven dimension is about 13?; inches wide 21 inches deep and 12 inches high, and that the 12 inch height is divided in two aperture of but 6x13} inches, into which the cook must thrust hand and arm to the depth of (at least) 18 inches in order to change the position of puddings, pies, etc., while being cooked in back end of oven.

To use the rack, the same is pulled into projecting position, as shown in the drawings, and the cooking vessels placed upon the grids 13. The rack is then pushed into the oven, forcing the guides 19 into "the guides 20, and the guides 18 back'into the guides 19, until the entire device'is housed inside the oven and the door 3 can be closed.

When the operation of cooking is finished, or as often previously as may be required, the door can be opened and the rack again drawn forward and the cooking vessels removed. The invention obviates the necessity of the cook inserting her arm into a heated oven in order to push the cooking vessels far enough into the same, or to insert her arm into the heated oven to take the vessels out; and much of the labor and inconvenience of cooking is thus entirely eliminated.

The object of making the bar 6 removable is to permit "the frame or rack to carry cooking vessels or viands, such as large roasts,

of greater height than the sides of the rack.

In such a'case only the lower grid will be employed. The upper grid will be taken off the rack and the bar 6 removed till the large vessel is on the lower grid. Then it willbe put back to serve as a handle for the frame.

by an iron shelf, thus leaving an and furnaces for. anything'that requires to' be heated in such places.

,I wish to have it understood that I may make such changes in the shape, size and arrangement of the parts as fairly fall within the scope and spirit of my invention. The construction shown constitutes, one embodiment only of my invention, and I do. not wish to be limited to the details thereof, ex-

cept in so far as is indicated in the accompanying claims.

Having thus described my invent-ion,I

claim as new and desire to secure by Letters Patent 1. A device of the kind described comprising a frame to be moved into and out of an oven, said frame including a U-shaped member located at the front thereof and a rectangular-shaped member located at the rear thereof, a removable bar connecting the ends of the arms of the U-shaped member together, members extending longitudinallv of said frame to join said U-shaped member to said rectangular-shaped member, and means carried by said frame for sup porting a plurality of grids thereon.

2. A device of the kind describedcomprising a frame to be moved into and out of an oven, said frame including a U-shaped member located atthe front thereof and a rectangular-shaped member located at the rear thereof, a removable bar connecting the ends of the arms of the U-shaped member together. members extending longitudinally of said frame to join said U-shaped member to said rectangular-shaped member, and grids removably carried by the top and bottom of said frame, the removal of said bar and said upper grid permitting articles of greater height than said frame to be carried by the same.

3. The combination of an oven, a frame to be moved into and out of said oven, means carried by said frame for supporting articles thereon, C-shaped guides for said frame mounted inside of said oven, C-shaped guides having telescoping engagement with the first-named guides and having lugs thereon. shoulders on the first-named guides adapted to be engaged by the lugs to prevent the second-named guides from being withdrawn from the first-named guides,'and a pair of tubular guides secured to the sides of the frame and having telescoping engagement with said second-named C-shaped guides, said tubular guides having lugs P thereon and shoulders on said second-named C-shaped guides adapted to, be engaged by I of an oven, said frame including a U-shaped member at one side and a rectangular shaped member at the apposite side, a re- I movable bar connecting the arms of the U-shaped member together, and members for connecting said U-shaped member to the rectangular-shaped member. 7 e

5. A device of the kind described comprising a box-like frame, means carried by said frame -for supporting a plurality ofgrids thereon, guides carried by the frame and extending along the opposite sides of the same,'members receiving said guides in movable bar forming the upper front edge of the'frame, guides secured to said frame along the sides thereof, members receiving said guides in telescoping engagement, and means for movably connecting said members to the inside of" an oven, whereby said frame can be moved into and out of said oven.
